When card second piston bar is retracted to lowermost end, the bottom surface of stripper plate is flushed with the bottom surface of punching hole, and the top of second piston bar is stretched
When out to top, the top surface of stripper plate is flushed with the top surface of punching hole；
D, before stripper plate is inserted into punching hole, annular coil pipe first is installed in the outside of punching hole, and by the two of annular coil pipe
End is separately connected water inlet pipe and outlet pipe, and water inlet pipe and outlet pipe are stretched out from the side of pedestal, by extension end and external cooling water
Equipment is connected and sealed, and intake pump is installed on water inlet pipe；
3) send mold mechanism is installed
A, bottom plate is horizontally mounted on the side of pedestal first, and the underrun reinforcement block of bottom plate is attached with pedestal,
Then two guide rods being parallel to each other of right angle setting and two fixed columns being parallel to each other, guide rod and fixation on the top surface of bottom plate
Column is distributed in quadrangle；
B, the lifter plate to match with bottom plate is then selected, first hydraulic cylinder is horizontally mounted on the top surface of the lifting plate, by first
Hydraulic cylinder is fixedly connected on lifter plate by locating piece, and the pushing assisted plate that selection matches with punching press platform passes through pushing assisted plate
First piston bar is attached with first hydraulic cylinder, and first hydraulic cylinder is connect by hydraulic oil pipe with external oil-servicing facilities；
C, two symmetrical through-holes are finally first opened up on lifter plate, and two guide rods are inserted into through-hole respectively, then edge
The bottom surface of lifter plate two telescopic rods for having rack gear are installed, two telescopic rods are arranged in parallel, while guaranteeing two telescopic rods
On rack gear direction it is consistent, will be successively horizontally inserted into two positioning columns with the transmission shaft of handle, make the gear on transmission shaft
It is engaged with the rack gear on corresponding telescopic rod；
4) continuous punching is tested
The continuous cooling water in external cooling water equipment is inputted in annular coil pipe by the intake pump on water inlet pipe first, simultaneously
Rotating handle makes the gear on transmission shaft that telescopic rod be driven to move up, and the scale on guide rod is observed, when pushing assisted plate reaches setting
Handle is fixed after height, starts the punch driving device in head, drives pressing block to liquidate flattening bench by boosting bar
On material carry out punch forming, pressing block rises under the action of boosting bar after punching press, start second hydraulic cylinder, make stripper plate
Stamping parts is driven to rise, until ejection punching hole, starts first hydraulic cylinder, stamping parts is pushed into next station by pushing assisted plate,
Stripper plate drops to the bottom of punching hole under the action of second hydraulic cylinder at this time, and pushing assisted plate contracts under the action of first hydraulic cylinder
It returns, carries out the processing of next stamping parts.
